1. Negative rake scrapers. I didn't even know they existed. They are very user friendly! I couldn't find a pre-ground one in the trade show, but one of the vendors showed me how to grind a regular scraper to a negative rake scraper.

2. How to cut a bowl blank from a log to get different grain patterns. And to get the maximum useable wood with minimum waste.

3. How to get a BEAUTIFUL CA finish on larger items. (He did it on a hollow form about 6 x 8"

4. Gisi's segmenting techniques for pens and other items

5. I've been grinding my bowl gouge incorrectly

6. My carbide tools can do WAY more than I thought they could

All in all, I had a great time and can hardly wait to try out some of my new techniques!

Can you elaborate on #6 a bit?
 
A negative rake scraper has a bevel on both the top and the bottom. It is used flat on the rest (not tilted) and with the handle level with the cutting edge (not "downhill" like a conventional scraper.

It is VERY forgiving. It rarely catches, it doesn't try to self feed, it leaves a smooth finish that almost feels like it has been sanded. It can remove tearout on endgrain. Most important, it doesn't take hours and hours to learn to use. I suspect there are several negative rake scrapers in my future!

I mostly use my carbide tools for turning pens that have turquoise infill because the stone ruins my HSS tools. I also use them for acrylic. But I saw people turning bowls, hollow forms, sculptures etc all with carbide tools. I'm going to get much more inventive with my carbide tools now.

Also if you grind the same bevel on both sides you can use it left or right or a better example of that is inside or outside of the vessel. All you do is put the burr on the opposite side.
